The effects of mechanical damage on residual coastal Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) following commercial thinning

Creator:: Kiser, James D.
Abstract:: Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

Taxonomy and systematic relationships of tui chubs (Siphateles: Cyprinidae) from Oregon's Great Basin

Creator:: Remple, Stacy L.
Abstract:: There are three recognized species of Siphateles from the Great Basin; S. alvordensis, S. boraxobius and the tui chub, S. bicolor. One species, S. boraxobius, is endangered and one population of tui chub at Hutton Spring is threatened. Despite several morphological and molecular studies, the taxonomy and relationships of tui...

Simulating Wood Properties in the Context of a Growth and Yield Model for Planted Douglas-fir

Creator:: Osborne, Nathaniel L.
Abstract:: Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...

Influence of habitat characteristics on Greater sage-grouse reproductive success in the Montana Mountains, Nevada

Creator:: Rebholz, James L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations have declined across their geographic range during the last century. They were once widespread throughout the Intermountain West, but lower annual productivity, likely caused by degradation and loss of suitable habitat, has greatly reduced their distribution and population densities. Habitat used for reproduction has been...

Gas-phase fragmentation chemistry of protonated peptide ions

Creator:: Bythell, Benjamin James
Abstract:: The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...

A monitoring system for identifying and recording land conversion in agricultural lands with SCS Soil Capability Classes I-IV

Creator:: Parker, Douglas Stuart
Abstract:: This paper discusses the structure, rationale, and application of a monitoring system specifically designed to identify and record conversion of lands with Soil Conservation Service Soil Capability Classes I-IV. Research methodology and design are structured to objectively assess the rates of agricultural land conversion to non-farm uses over a given...

Variations in Alsea River flow: implications for Alsea Spit & inlet stability

Creator:: O'Neil, Douglas James
Abstract:: Based in part on previous work by this researcher, variables assumed to play a minor part in the process/ response system examined by the OSU Alsea Bay Hazard Study Team (1985-87)--river input and subsequent variations in hydrology--were more completely analyzed for their range of effects on the stability of Alsea...

Houses of fiction, houses of confinement : character introductions, autonomy, and domestic spaces in two works by Henry James

Creator:: Killips, Lisa M.
Abstract:: My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...

Luminescent sulfides and solution-deposited oxide thin films

Creator:: Anderson, Jeremy T.
Abstract:: Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

Proteomic approach to the analysis of DNA-binding proteins using mass spectrometry

Creator:: Stapels, Martha Degen
Abstract:: In proteomic studies, separate experimental protocols have been necessary to identify proteins, determine their function, and predict their three-dimensional structure. In this study, a function-based separation of proteins was conceived to fractionate proteins prior to enzymatic digestion. In the initial demonstration of this technique, a DNA substrate was used to...
